| As described in <https://pcrebuilding.altervista.org/9/download/57a34d9c0195f_SUPERMICRO_P55T2S_jumper_settings.pdf>, the external battery header pinout is as follows: | |
| JP30: Optional External battery, pin1: +3V, pin2 and pin3: No Connect, pin4: Ground | |
| Note: pin3 (GND) is nearest the ATX power connector (top end of board in tower configuration). | |
| I have had success removing the soldered battery and connectng a battery pack containing 2x AA batteries in series (+3V) to this connector. | |
| Note that if 3x AA batteries are used (4.5V), the machine will not boot. |
